Numerical analysis of the influence of the channel cross-section aspect ratio on the performance of a PEM fuel cell with serpentine flow field design

Effect of different flow field designs and number of channels on performance of a small PEFC

“…Since it has been widely known that a uniform distribution of water content leads to a better cell durability [19], many researchers [39,40] have tried to develop the flow fields which give the uniform distribution of membrane water content. In addition, it has been also known that the cathode side of the PEFC associate with the water flooding problem, and thus Fig.…”

The effects of channel depth on the performance of miniature proton exchange membrane fuel cells with serpentine-type flow fields

“…Therefore, the effects of channel depth for various rib widths are theoretically similar to the results described above. On the other hand, Manso et al [19] numerically investigated the effects channel depth-to-width ratio using ten different channel geometrics. Their results reveal that the cell performance increases for higher channel depth-to-width ratio if the ratio value is less than or close to one.…”

“…Simulating a 24.6-cm 2 cell revealed that the performance of a PEMFC with a serpentine flow channel is insensitive to channel depth in certain operation conditions [3]. In the simulation of a 2.56-cm 2 miniature cell, the results indicated that cells with a high aspect ratio yield higher current densities [19].…”

Influence of geometric parameters of the flow fields on the performance of a PEM fuel cell. A review

“…P. Manso et al [87] numerically analysed the influence of 10 different channel cross section ratios varying between 0.07 and 15 (Fig. 21) (height of channel C H to width of channel C W ratio) on the performance of a PEM fuel cell with serpentine flow field (SFF) design.…”
